GEORGE W.BAKER, or CLEVELAND, 01110, ASSIGNOR- TO WHITE SEWIN MACHINECOMPANY, OF SAME PLACE.

TAKE- FOR. SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 224,572, dated February17, 1880.

Application filed October18,1879.

.To all whom it may concern:

Be it known that I, GEORGE W. BAKER, of Cleveland, in the county of(luyahoga and State of Ohio, have invented certain new and .5 usefulImprovements in Take-Ups for Sewing.

, Machines; and I do hereby declare the following to be a full, clear,and exact description.

of the invention, such. as will enable others skilled in the art towhich it pertains to make and use it, reference being had to theaccompanying drawings, which form part of this specification.

My invention relates to sewing-machines, and more particularly todevices for regulat- 15 ing and takingmp the slack of the thread betweenthe needle and spool or tension device; and it consists of the followingparts and the construction and combination of parts, as hereinafterspecified and claimed.

In the drawings, Figures 1, 2, and 3 illustrate my device in the variousstages of its operation, and Fig. 4 is a side elevation of my device. y

In the said drawings, Ais the face-plate of a sewing-machine; B, theneedle-bar, and (l a slot made through the face-plate for theaccommodation of alug or arm, B, which connects the needle-bar with mytake-up device,

whereby said device is actuated by the motions ofsaid needle-bar. D D isan angular lever pivoted to the rocking lever E. The-angular rockinglever E is pivoted to a plate, E, adjustably attached, by suitable slotand setscrew connection or otherwise, to the faceplate A. Each end ofthe angular lever E and the free arm D of the angular leverD D areprovided with holes, loops, or suitable passages for the thread F. Thisthread is led through my device as follows: From the spool it passesfirst through the short arm of the lever E,

thence through the free arm D of the angu-.

lar lever D D, thence through the longer arm of the lever E and down tothe needle. The

angular lever D D is loosely or pivotally at- .tachedboth to theconnection B and to the angulari lever E, the latter being pivoted tolever D.D at the junction of its two arms. It will therefore be seenthat as the needlebar moves up and down'it will carry the lever D D upand down with it by means of the connection B. It will also be noticedthat by the construction already specified the free arm D of the angularlever D I), at every complete movement of the needle-bar B, whetherupward or downward, will be caused to twice pass over the face of thelong arm of the lever E; and it will further be noticed that the arm Dof the angular lever D D serves as a link to connect the needle-bar Bwith the lever E, whereby these two parts may operate in proper concertand connection with each other.

The object of my device is to slacken the needle-thread during thepassage of the me dle downward through the. fabric. If the thread ispermitted to draw taut upon the needle during that time, it is liablenot only to break itself, but by pulling the needle out ofline itresults in poor work and in a liability tobreak the needle. It istherefore desirable that the thread should be loose in the needle as itpasses downward through the fabric; and to accomplish this is theprincipal object of my device, whose operation is as follows:

Referring to the drawings, Fig. 3 illustrates the parts as in theposition assumed when the needle is at the limit of its downwardmovement. Fig. 2 represents the position of parts when the needle-bar isbetween its extreme up and down movement; and Fig.

1 shows the position of parts when the needlebar is at its extremeupward movement.

. As the needle-bar moves upward the thread is drawn taut from needle tospool until the parts assume the position shown in Fig. 2, where the armD is in position directly over the long arm of the lever E. Theneedle-bar has not yet reached the extreme of its upward movement, butin doing so (see Fig. 1) the arm 0 D is moved beyond the arm of lever E,and by this movement an additional length, F, of the thread F is drawnout. As the needlebar now moves downward to make the next succeedingstitch this length F of the thread 5 becomes so much slack above theneedle, and the needle is therefore freed from strain and permittedfreely to pass downward through the fabric.

The degree of movement of the various parts roo the second lever beingprovided with threadguides, substantially as set forth.

2. The combination, with the face-plate and needle-bar of asewingmachine, of an angular lever, one armof which is pivoted to theneedle-bar, and a second lever, the fulcrum of which is connected to theface-plate and one arm of which is pivoted to the first lever, thefreeextremities of both said levers being provided with thread-guides,substantially asset v .forth. Y

3, The combination, with the slotted faceplate, and needlebar of asewing-machine and a pivot projecting from the latter through the slot,of an angular lever, one arm of which is connected to said pivot, andasecond lever, the fulcrum of which is connected to the faceplate and onearm of which is pivoted to said angular lever, substantially as setforth.

4. The combination, with the slotted faceplate and needle-bar of asewing-machine and a pivot projecting from the latter through the slot,of-an angular lever, one arm of Whichis connected to said pivot, and asecond angularlever, the fulcrum of which is adapted to be adjusted onthe face-plate and one arm of which is pivoted to said first lever, thefree extremitiesof both levers being provided with threadguid'es,substantially as set forth.

5. The combination, with the face-plate and needle-bar of a sewingmachine and an angular lever, one arm of which is pivoted to-theneedle-bar, of a second lever formed with a long arm and a short arm,thefulcrum of this second lever being connected to the .face-plate andsaid long arm being pivoted to the first lever, the free extremities ofboth levers being provided with thread-guides, substantially as set.forth,

6. The combination, with the face-plate and needle-bar of asewing-machine and an angular lever, one arm of which is pivoted to theneedle-bar, of a second angular lever, the fulcrum of which is connectedto the face-plate, and one arm of which is pivoted to the first lever atthejunction of its two arms, the free extremities of both levers beingprovided with thread-guides, substantially as set forth.

In testimony whereofl have signed my name to this specification in thepresence of two subscribing witnesses.

' GEORGE W. BAKER.
